Abstract: The present invention relates to a wasteless method of a single stage hydrolysis of lignocellulosic materials with a transformation reaction to product wherein the method is characterized by mechanical preparation of a raw material followed by a thermal-pressure hydrolysis. After finish of the hydrolysis reaction, the suspension is expanded in a single phase to yield a steam fural phase and a hydrolyzate containing hydrolysis fermentable sugars, lignin and water. The invention is further characterized by higher yield of the fermentable sugars, whereby after separation of lignin, the sugar phase is used directly in the preparation of a mash in an onward fermentation process or it is supplied for an enzymatic hydrolysis. After finish of the enzymatic hydrolysis, there are obtained hydrolysis fermentable sugars and particularly lignin. The solution of the fermentable sugars is supplied to the mash preparation system. Subsequently, the fermentation process thereof takes place. A substrate containing ethanol is distilled; the thus obtained raw ethanol is refined or freed from residues of water on molecular sieves. The obtained anhydric bio-ethanol is subsequently used for the production of electric power. 05.02.2014	PV	udelení	2012-759	304262	B 65 G 65/28	Bejlek Václav Ing., Cernosice, CZ Device for uniform dispersion of dust partic les In the present invention, there is disclosed a device for uniform dispersion of dust particles consisting of a drive shaft (8) passing over into a stem (2) of a dispersion disk (1), which is provided from above with disintegrators (7); in its middle and lower portions it is provided with a worm (6) and in its bottom portion it is provided with the dispersion disk (1) comprising proportioning blades (3), which have their longer side attached to said dispersion disk (1) surface (1) while the lateral side thereof is attached to the stem (2).

A soil sample disperses in the solution of Ki2Cri2Oi7 in Hi2SOi4, gradually oxidizes, and in continuously taken measuring samples of the suspension, there are determined values of oxidizable carbon CiOX1 through CiOXn and the final value of CiTOT. The CiOXn value determines the amount of the primary organic material, the velocity constant (K) of the gradual oxidation kinetics K = 2.303.tg{alpha} determines the quality, wherein {alpha} is an angle of the gradual oxidation segment (p) formed by the values log (CiTOT - CiOX1) through log (CiTOT - CiOXn). The amount of humus is determined as a humification degree S=100•(CiTOT - CiOXn)/CiTOT, and the humus quality is determined by the Sandhoff method as a difference of the ion-exchange capacity of a soil sample prior and after oxidation with hydrogen peroxide. 05.02.2014	PV	udelení	2012-843	304266	D 01 D 5/06	Beták Jirí, Dolní Újezd, CZ Endl ess fibers based on hyaluronate selectively oxidized in position 6 N-acetyl-D-glucosamine portion, their preparation, use, threads, yarns, fabrics and process for preparing thereof The present invention relates to a process for preparing textile-treatable endless mono- and miltifilaments based on aldehyde-modified hyaluronate in position 6 of its N-acetyl-D-glucosamine portion and their subsequent surface treatment using low-molecular dihydrazides. Fibers and consecutive fabrics prepared therefrom exhibit a time-variable dissolution period within a physiological solution in dependence on their surface finishing. After surface treatment, the fibers and fabrics have a prolonged transition time to a uniform gel layer. Through surface modification of fibrous materials, the complete biocompatibility of materials is maintained. 05.02.2014	PV	udelení	2012-844	304267	C 08 B 37/08	Bobula Tomás Ing., Svit, SK Photoreactive derivative of hyaluron ic acid, process for its preparation, 3D crosslinked derivative of hyaluronic acid, process for its preparation and use In the present invention, there is disclosed a photoreactive derivative of hyaluronic acid (of the general formula I) and process for its preparation wherein the preparation process is characterized by the preparation of a hyaluronic acid derivative in the form of aldehyde in position 6 of the glucosamine cycle, which is subsequently reacted with an amine carrying a pyridone skeleton (a photoreactive particle), such as 1-(2-aminoethyl)pyridin-2(1H)-one, in the presence of a reducing agent to form a photoreactive derivative. The so prepared photoreactive derivative can be subsequently photochemically crosslinked through the mediation of [4+4] photocycloaddition reactions. The present invention further relates to a 3D crosslinked hyaluronic acid derivative (of the general formula II), which exhibits increased hydrolytic stability and enhanced sorption properties, with possibilities of further design of their physical properties according to the requirements of the final applications and further its use in tissue engineering, regenerative medicine, pharmaceutical compositions, or cosmetics. 05.02.2014	PV	udelení	2012-850	304268	G 01 N 31/22	Králík Lukás Ing., Jedovnice, CZ Detector for colorimetric detection of m ethylsalicylate presence in atmosphere In the present invention, there is described a detector for colorimetric detection of methylsalicylate presence in atmosphere wherein the invention is characterized in that the detector consists of a fabric of natural silk impregnated with a detection agent containing a solution of ferric chloride in concentration in the range of from about 5 to about 40 percent (m/V) and a macromolecular additive in concentration of from about 1 to about 40 percent (m/V) in ethanol. This detector can be used for the determination of barrier properties of protective aids and is usually arranged within a space separated by the protective aids from the space with methylsalicylate, which can be in concentrations from trace to saturated ones. The macromolecular additive can be polyethylene glycol crosslinked within the range of a molar weight from about 2000 to about 10 000, but also another type of a macromolecular substance of similar density. The methylsalicylate exhibits some physical-chemical features similar to the physical-chemical features of the mustard gas casualty agent or that of other hazardous chemicals. However, due to significantly lower toxicity, it is used in tests of barrier properties of protective aids, exactly instead these hazardous chemical agents. 05.02.2014	PV	udelení	2012-869	304269	B 04 B 1/20	Kutil Josef Ing., Podebrady, CZ Appara tus for mechanical thermal disintegration of biological, centrifuge-thickened sludge The apparatus for mechanical thermal disintegration of biological, centrifuge-thickened sludge according to the present invention consists of rotating components located on a centrifugal basket, and a static portion coupled fixedly with the centrifuge cover.
